Dumbledore? He knows nothing about MC alchemy.

The few little wizards who were giggling on the third floor also quickly went downstairs and looked at the big hole in the ceiling...

"This shouldn't be the case, Sirius. Doesn't the Black house have that kind of gravity protection magic?" Hermione asked doubtfully.

"This should have nothing to do with gravity." Cedric controlled the robotic arm behind him and directly controlled the robotic arm to carry him down.

Then he squatted down and picked up a cracked piece. He just squeezed it lightly and it turned into slag.

"It should be due to thermal expansion and contraction. Because the temperature difference is too big, the part that supports the bottom of the smelting furnace was completely shattered into slag, and then this happened." Cedric explained.

"Oh, don't worry about those trivial things. Kaisen will fix the ceiling and the floor upstairs anyway. Let's continue playing." Sirius waved his hand, cleaned up all the dust and debris on the ground, and sat back on the sofa.

"Where were we just now?"

"It's okay, Cedric... Sirius is just like that, he won't care about these things." Harry walked over and patted Cedric on the shoulder, indicating that he shouldn't care about these trivial matters.

"Well... I don't care. It's just a necessary explanation, not a so-called excuse." Cedric still explained.

At this time, Grindelwald finally came out of the kitchen: "Clear the table, it's time to eat."

The artist drew this beautiful second creation. I will tag the artist in the comment section of this sentence. If the artist gets there first, please tag me and give me a great review.

Chapter 363 Conversation at the dinner table

The sweatshop moved from upstairs to downstairs, and after Kaisen finished making the main body of the robotic arm, he continued to study other components using other materials.

This component must be carefully considered. Recall that before Kaisen traveled through time, he played an MC Craftsman's Soul integration pack. That integration pack locked the original tools, so Steve could not use them and could only use the Craftsman's Soul.

He took it for granted that stone was stronger and more durable than wood, so he foolishly used stone to make binding knots and handles.

Both of these things are special features of Craftsman Soul, and are basically equivalent to tool making in the real world, but everyone should be able to understand them.

Stone is brittle.

So when Kaisen plays, a pickaxe made entirely of stone can only dig one stone, so when he needs to make a furnace, he needs to carry a full eight pickaxes in his backpack.

However, at this moment, an older sister pointed out Kaisen's mistake, and he realized...

The parts in the Craftsman Soul module have durability.

Damn retard............

So this time Kaisen learned his lesson and began to carefully calculate the durability of each component.

Otherwise, Kaisen would use his mechanical arm to kill Voldemort arrogantly, and then just shatter into pieces...how embarrassing.

Just as Kaisen was carefully writing and drawing on the parchment, Grindelwald suddenly appeared behind him.

"Didn't I just tell you...to go have dinner?" Grindelwald said dimly.

The deep voice instantly gave Kaisen a chill. He turned back stiffly, like a child telling his parents to wait until he finishes this one. He also said stiffly, "I'll finish the last one."

Grindelwald, like everyone's parents, put his hands on his hips and shook his head: "No."

Then he patted Kaisen on the shoulder and was about to pull him up.

"Oh, okay, okay, I'm coming, I'm coming." Kaisen stood up naturally and walked towards the restaurant. After sitting down, he naturally held hands with others and sang songs.

After the song was finished, Kaisen slowly asked a question.

"As wizards, why should we praise God? Didn't his followers kill wizards miserably?"

"........................"

Kaisen's words silenced everyone present without him realizing it. He continued to babble about random things until Snape walked out of the fireplace and sat next to Kaisen, and then he finally shut up.

Because Snape was tired of listening to it and was pinching his legs hard from below.

"OK, OK, let's eat. I won't say anything more." Kaisen rubbed his thigh and slowly picked up the knife and fork.

The meal didn't go on very quickly because there were so many people.

There are many wizarding families and a large number of little wizards, and when these adults and children sit at the same table, there is always one topic that cannot be avoided.

For example...

Mr. Longbottom spoke first: "You are all grown up now. Do you have any plans for the future?"

Ginny, the only relatively young girl present, lowered her head silently, trying to dress herself up as the red jam on a plate.

The other young wizards looked at each other and said, "Maybe...Aurors? I always thought Aurors were cool."

"Harry, with your grades, you may still have some distance to go before you can become an Auror, but I think your qualities will undoubtedly make you an Auror," said Kingsley, the Auror himself.

As for the other Aurors present, Moody had been retired for a long time and was certainly not normal.

Mr. Longbottom was even more of a heavyweight, having spent twelve years in St. Mungo's. His views on the current state of the Auror profession were even worse than Moody's.

"What about you guys? Let me start with you, George Weasley and Fred." Mr. Weasley also took over the conversation and asked.

"Joke shop." Gemini said quickly.

"I don't think..." Mrs. Weasley had just begun to speak when the Weasley twins retorted: "Mom, look at Percy."

"Do you really want us to go into the Ministry and end up like that?"

The twins said in unison. Percy, who was sitting at the other end of the table, lowered his head in shame, just like Ginny.

Ever since the last time he was sent on a mission by Fudge, he was told when he came back that Fudge was dead and Umbridge was killed. The people from Fudge's faction scattered, some were imprisoned, and only a few big cats and small cats were left, and he was the biggest one.

Because in addition to being a low-level employee, he also works part-time as a cigar buyer for the Minister of Magic's Office.

But the new minister Barty Crouch doesn't really smoke...

"The Ministry of Magic can't be said to be a good place to be." Percy raised his head and said dryly.

"Look, our dear brother has said so, how could he be wrong?"

Mrs. Weasley was choked by the two and was speechless. She turned her head and looked at the next victim: "Ron, tell me your story?"

"Maybe a Quidditch player. Anyway, I was selected for the Gryffindor Quidditch team."

Ginny was lucky enough to escape because she was too young, and then it was Cedric and Neville, their parents looked at them curiously.

"Well...alchemy shop!" Cedric said firmly.

Now Neville is the only one left.

His face flushed a little in embarrassment: "Maybe... I haven't thought about it yet."

Professor McGonagall coughed and said, "I need to remind you, Neville, you are now in your fifth year. It's time to consider the advanced classes for sixth and seventh years. It's still difficult for OWLs to find a decent job nowadays. Perhaps you can think about your strengths, such as Herbology, Charms, and even Alchemy."

"I'll consider it, Professor... Professor Kaisen, if I want to take the advanced alchemy class..." Neville nodded and looked at Kaisen.

"I haven't set any limits for the Alchemy Advanced Class, but the timelines for sixth and seventh graders are tight. If studying Alchemy will infringe upon the subjects you really want to study, I don't recommend it," Kaisen explained.

Chapter 364 Bone Replacement

"Oh... okay." Neville said a little aggrieved when he heard what Kaisen said.

Fortunately, this was just a small episode, and the overall atmosphere of the dinner was still very good. Even Sirius and Snape didn't talk trash to each other.

Although this was also because the two of them were seated very far apart, and Snape left after having a light meal that lasted less than an hour.

He had been at the Black house for less than an hour.

Perhaps if he didn't have the double agent certification jointly certified by Dumbledore and Voldemort, and Voldemort needed him to attend this dinner to steal information from the Order of the Phoenix, he would not have set foot here at all.

The Christmas holiday is extremely pleasant. Before, I often lived alone at home or in the office, but now I suddenly have some group accommodation. The room is my own private space, and outside the room there are bustling noises. This lively feeling is also nice.

What's more, he has three more young and strong cattle and horses.

...................................

That day, Kaisen finally debugged all the parts to the best condition, and only then did he drive Cedric and the Weasley twins out.

By the way, let them invite Dumbledore over.

Soon, Dumbledore arrived at Kaisen's room. He looked at the Netherite skeleton and the mechanical arm in the room and raised an eyebrow: "So you still need my Slicing Charm this time? And then you slowly move in by yourself?"

Kaisen shook his head: "No, of course not, this time the netherite skeleton is an upgraded version."

Dumbledore breathed a sigh of relief upon hearing this.

"I need you to tear me apart, take out my original bones, and then put these bones in." Kaisen said calmly.

"......................Clam?"

Kaisen raised an eyebrow. "Is it hard to understand? Besides, for a wizard, it should be very simple."

Dumbledore shook his head. "If that's the case, and not fusion, then it's indeed simple. I'm just a little surprised at how this method came about in your mind. It's rather... a little too bizarre."

Kaisen smiled awkwardly and then lay down on the stone platform. This way, if he bled, he would only need a cleansing spell and would not have to change the sheets.

Dumbledore soon composed himself and began to work.

For example, an ordinary bone-pulling spell can pull out the original bones with a layer of iron skin, and then move the netherite bones in using space magic.

An adult has a total of 206 bones, so this is a very large project.

afternoon.........................

Kaisen sat up from the stone platform, moved himself casually, and controlled the mechanical arm behind him. There was a subtle sense of sluggishness, but that was not enough to be reliable. He just needed to use it for a few more days to let it adjust.

After many days, he once again put on the specially made shirts and coats that he had ordered before. The cool breeze blowing from behind made him shiver comfortably again.

"This feels really good." Kaisen sighed in a daze.

"That's good? You're stronger?" Dumbledore asked.

"For example, if you had twelve arms before and suddenly lost ten of them, you would feel like you have too many brains to use. But now, that bloated feeling in your head is gone." Kaisen thought for a moment and described it to Dumbledore.

"Is that so? If you want to know, maybe you can try cutting off one of my fingers, then I might understand how you feel." Dumbledore said with a smile.

"You'll just feel what it was like when I lost my robotic arm," Kaysen added.

"At worst, I can reattach that finger. It's pretty easy." Dumbledore shrugged and looked at the pile of bones that had been removed from Kaisen. "Those bones can be said to be another you. Any ideas?"

"No ideas? Does Hogwarts need a skeleton teaching aid? You can use it as a teaching aid." Kaisen said casually.

"Okay." Dumbledore waved his wand, and the pile of bones moved and reconnected with each other, finally becoming a skeleton. He grabbed a handful of Floo powder by the fireplace and threw it into the fireplace, then walked in.

"...............He has no vocal cords, how can he get back to Hogwarts?" Kaisen asked in confusion.
